At a time when climate change is forcing us to rethink the way we live, the Subtle Shifts project designed by Steffan Welsch Architects shows how thoughtful design can turn a tired, inefficient house into a comfortable, low-impact family home with adaptability—without adding a single square metre.
This modest Californian Bungalow in Melbourne had been altered over decades, leaving it with a fragmented layout and underused spaces. But instead of knocking down walls or building out, the design team took a different approach: they looked inward. What followed was a quiet but radical transformation and a reshaping of space that prioritised connection, adaptability, and sustainability.





The idea was simple but powerful: move away from the outdated “one room, one function” mindset and start designing for flexibility. That meant combining the kitchen, living, and circulation areas into one central hub—a sunken communal space that feels warm, welcoming, and versatile. It’s where daily life unfolds, where family and friends gather, and where movement flows effortlessly between rooms.
This single gesture did more than improve flow—it gave the house a new heart. It also allowed the team to rezone and rework the existing floor plan. A once-oversized bathroom became two separate spaces: a compact bathroom/laundry and a guest room that doubles as a study. These subtle shifts unlocked layers of functionality without increasing the footprint.

Sustainability Features
- Retained existing footprint (no additional built area)
- Designed for adaptability to changing needs with multi-functional spaces
- Recycled materials
- Solar passive design
- All electric
- Indigenous, climate resilient planting
- Upgraded building fabric beyond regulatory requirements
- Low VOC materials
- Cross ventilation for passive cooling
- Double glazed timber windows + doors
- Solar panels, battery and heat pump


And that’s the beauty of the project – sustainability is at its highest when you’re using what you already have—and using it better.
Every design choice was made with low-impact living in mind. By reworking the existing structure, demolition and waste were kept to a minimum. Recycled bricks, reused timbers, and low-VOC materials were used wherever possible. The home is all electric, with solar orientation, passive ventilation, and an upgraded building fabric that exceeds code requirements—all helping to slash operational energy use.
Outside, the front yard was reshaped and replanted with indigenous species, creating a small but meaningful pocket of biodiversity that also manages stormwater and cools the microclimate.


What emerges is a home that’s deeply personal, flexible, and efficient—one that works just as hard for its occupants as it does for the planet. It’s not about chasing a particular style or pushing for more space. It’s about restraint, creativity, and intention.
Subtle Shifts is a case study in how intelligent, climate-conscious design doesn’t have to be loud or expensive to be effective. It’s a reminder that building less can actually mean living more—and living better.
